1. Flow Network - Linear Optimization

Thanks, Hopefully I will be able to solve the rest ;)
2. Flow Network - Linear Optimization

x1= -20 + x5 + x6 x2 = 50 - x5 -x6 x3 = 40 - x6 x4 = 10 - x5 x5 = free variable x6 = free variable -20 + x5 + x6 ≥ 0 50 - x5 - x6 ≥ 0 40 - x6 ≥ 0 10 - x5 ≥ 0 x5 ≥ 0 x6 ≥ 0 Do you mean this?
3. Flow Network - Linear Optimization

Here is the pipe flow network. [PLAIN]http://img36.imageshack.us/img36/8287/pipes.png [Broken] After I have found the 6 inequalities, the assignment asks me to write them as inequalities for x5,x6 or x5 + x6. Then to minimize flow between D and E. I have to use Linear Programming to find the...
4. Flow Network - Linear Optimization

Homework Statement I am doing an assignment in my Linear Algebra class. But I don't know how I will go about solving this problem. So the problem is a network of water pipes. I start with a matrix and I get the solution to the system from the RREF matrix. All the flow directions are set, so...
5. Find Thevenin equivalent

Wow.. I hope you are kidding, if not, I am so sorry ;(:cry:
6. Find Thevenin equivalent

Also, is there any other method of doing this other than Loop Current method, Node Voltage method and Branch Current method? Can you use something else, like superposition? It doesn't say so I am completely lost as to what exactly I need to calculate things with.
7. Find Thevenin equivalent

I gave up.. seems I cannot do it. If anybody is capable and kind, and has enough time to do this I wouldn't mind. It would make me super happy! I want to be able to get this assignment.
8. Find Thevenin equivalent

Hi, thanks for help! But I am stuck as ever. I know I have to redraw and remove RL but I am uncapable of doing so. I must be an idiot that doesn't see it. I also have no idea how to exactly calculate voltage across the terminals RL is connected to. I tried to use superposition and found...
9. Find Thevenin equivalent

Homework Statement This is in norwegian but hopefully you can understand it. Here is the assignment and circuit: http://img835.imageshack.us/img835/3619/krets.jpg [Broken] Find the equivalent Thevenin circuit when when RL is the load Homework Equations The Attempt at a Solution I really...
